Help Wi-fi...killer of batteries...

[asevie]

Just gave up the iPhone 4 for a Skyrocket. Initially I was shocked at how pathetic the battery life is but have tweaked my way to a more manageable day. First off, I was stunned that wi-fi would drain the battery as quickly as it does. From everything I read I assumed LTE would kill the battery and I was going to be very proactive about connecting to wi-fi wherever I went. With a brand new phone and a full charge at 9am I would find my battery down to less than 30% by 2pm (with very little use at all of the phone or data, maybe 15 minutes of phone time and less than 10 minutes web/app use). Turning wi-fi off made a massive difference. With wi-fi on the phone would drain about 10-12% of the battery per hour. With wi-fi off the phone only loses about 3% of its battery life per hour. I can now go 20some hours with average use of the phone and data.

you can change the wifi setting to turn off while the screen is off, to save on battery

Yes. Open wifi settings menu.advanced



The developers on xda have seen this wifi issue as well but I don't know that anyone has found the cure

Might try that. I use the phone in my houe 90% of the time and leave wifi off most of the time cause I just forget to turn it on for data intensive applications. I'll see how the drain is.

Yea I figured this out recently too! The Wi-fi drains the battery extremely fast. I would end up in the 20's by night time with a 100% charge, even if I didn't use the phone much except for a few text messages or phone calls.

 

[Mr. Ed]

are you guys actually connected to wifi when this happens?

I know one issue that has been seen is that the phone does not go into deep sleep ...this may be on 2.3.6 only...

what software version is your skyrocket on?

i hear rooting it and freezing wifi share greatly will improve battery life

I work out of the house and am on Wi-Fi almost all the time. My battery typically drains from 3-5% per hour when I am not using it much, if at all (other than it just sitting there while I work). Not sure why yours was draining 10%+, but I have definitely not seen that while I am on Wifi.
